Noblesville Police Lt. Bruce Barnes said the victim, Aubrey Peters, of Noblesville, was shot in the chest and later died at St. Vincent Hospital.

The shooting was reported at roughly 11:30 p.m. in the 8200 block of River Run Place. When officers arrived at the home, they found Peters unresponsive.

Jacob McDaniel, 20, has been charged with reckless homicide, and a not guilty plea was entered on his behalf in court Monday.

The probable cause affidavit said McDaniel removed a gun's magazine, pointed the gun at Peters, took the safety off and pulled the trigger.

According to court documents, after being shot Peters clutched her chest and said, "What just happened?"

Peters' grandfather, Randy, who has raised her since she was 8 months old, said the family is devastated.

"She had a 3.9 GPA. A great student, a great kid," he said.

He said he doesn't know what happened and doesn't know McDaniel. He said his granddaughter left home Sunday to study.

The American Red Cross of Greater Indianapolis honored Peters in 2011 for helping to save two young girls who had fallen through the ice on Morse Reservoir the year before.

Peters, then a seventh-grader, told investigators she heard the screams of 7-year-old and 4-year-old sisters and alerted her grandparents and called 911. One girl reached shore safely, but Peters' grandfather pulled the other out and resuscitated her.

Ann Gregson, with Red Cross, said she remembers Peters well.

"Our hearts are broken here," Gregson said. "It is always a treat to honor young people. She stood out. They always do when they are younger, you remember. Anytime there is a senseless death it breaks your heart. We are thinking of her family."
